Complete guide to mineral and chemical sunscreens for families. We break down active ingredients, application reality, and reef-safe claims to help you protect your family effectively.
Mineral sunscreens (zinc oxide, titanium dioxide) are the safest choice for young children and sensitive skin, with the tradeoff of white cast and thicker application. For older kids and adults, modern chemical formulas can be safe and more cosmetically elegant when reef-safe ingredients are selected.
